T all whom it may concern:

Be it known that I, YAICHIRO SHIT subject of Japan, residing in San. Jr county of Santa Clara, State of California, have invented certain newand useful improvements in Automobile Signals, whereof. the following is a specification.

This invention relates to auwmobile signals, to indicate when the machine is about to stop, or which way it is about to turn.

To such ends the invention comprises an arm which may be projected outward from the machine, either straight out, or at an angle, its position, when so projected, giving the intended signal. The invention includes mechanism by which the arm may be operated, to the above ends. The invention includes also aseries of lights in a line, preterably on the arm, which give a position signal at night.

I have fully illustrated my invention in the accompanying two sheets of drawing, in which I have shown a mechanism contaming it, and in which Figurel is an elevation of the mechanism, as seenby the driver of the machine to which it is applied, and shows the signal arm projected at right angles, with its posi. tion when entirely retracted indicated in dotted lines.

Figure 2 is a top View of the same.

Figure 3 is a partial sectional elevation, the section being taken on the line a, a, of Figure 1 looking in the direction of the arrows.

Figure 4 is a section on the line b, b, of Figure 3 looking in the direction of the arrows.

Figure 5 is a section, on a larger scale, on the line 0, c, of Figure 2 looking in the direction of the arrows.

In the ligures;-The apparatus is shown as attached to rail of the windshield oi an automobile, 1 being the side rail portion and 2 the glass portion. To the side rail portion, 1 is attached an upright bar 3, by means of clamps a, which may be fastened by a thumb nut and bolt 5. A bracket 6 is supported by the bar 3, and is made rigid therewith in any convenient manner, by notches 7 engaging teats 8 on the clamps 4. An arm 9 is pivotally connected to the bracket 6 so that it may hang downward against the face of the bracket, as appears on dotted lines in Figure 1, or may be swung in that figure.

The mechanism tor opera ng 9 is as i'ollows:A plate 10 pro ects o .ckward from the upper part oi bracket 6, and has a ircular edge 11, with notches l2 and 12 therein. At the center of the circle forming the edge is an. arbor 13, which, on one side of the plate 10 carries a pinion 14-, and. on the other side, a crank 15, with. a handle 16. A. pinienl'. attached. to arm 9, enmeshed with pinions 14, whereby a movement of crank 15, determines a swing of arm. 9. A combined housing and bearing plate iLSis secured to plate 10, and serves to cover pinion 14; and provide a bearing for the itbOl 19 upon which arm 9 and pinion 17 oscillate. The crank is provided with a projection 20 and lip 21, embracing the edge of plate 10. A dog 22, pushed outward by a sprin,-.2j 23, housed in a hole in the projection. 32?, engages the notches 12 and 12, and holds urn 9 in the position corresponding thereto.

In practice, arm 9 normally hangs down, as shown in the dotted lines of Figure 1. When. it is desired to give a signal crank is operated, and, through pinions and swings arm 9 outward into one of the three positions indicated by the three notches 12. The particular signal given will be tired by the rules of the road. For example; straight out as shown in Figure 1 may mean Left which may be indicated by the letter L stamped upon the circular edge 11 as shown in Figure 3 out with a downward inclination may mean Stop indicated by the letter S stamped upon the circular edge 11, and out with an upward inclination may mean Right indicated by the letter R also stamped upon the circular edge 11, and the notch 12, is for the purpose of holding the arm 9 out of operative position as shown in dotted lines Figure 1 and stop pin 24 is to limit the'movement of the crank 15.

Having thus described my invention, and an embodiment of it, in the full, clear and exact terms required by law and knowing that it comprises novel, useful and valuable improvements in the art to which it pertains, I here state that I do not wish to be limited to the precise construction and arrangement or the several parts, as herein set forth, as the same may be variously modified by a skilled mechanic without departing from the spirit of the invention.

connected to one of said pinions adapted to. move said arm, means on said lever en- .said plate and adapted. to retain said arm in a predeterminate position.

2. An automobile signalling device comprising, in combination, a bracket adjustably mounted upon the wind shield rail of the automobile, an arm pivotally connected to said bracket and concealed thereby when not in operation, said arm adapted to swing upward, and outward from said bracket, means for operating said arm, consisting of a plate projecting from said bracket, a pinion on said arm and a second pinion on said plate engaging said first pinion, a lever pivotally secured to said plate and engaging said second. pinion, means on said lever engaging the upper edge of said plate and adapted to retain said lever in a predeterminate position.

3. An automobile signalling device, comprising, in combination an upright bar secured to the wind shield rail of the automobile, a bracket adjusta'oly mounted upon said upright bar and supported thereby. an arm pivotally connected to said bracket and adapted to swing upward and outward therefrom, means for operating said arm, consisting of a plate projecting backward from an I claim and desire to secure by Let.

said hr; and providedwith notched edge, an arbor journ'ally upon said platefa pinion and a crank secured to said arbor, a pinion secured to said arm and engaging said first pinion whereby a movement of the crank determines a swing of said arm, a dog on said handle adapted to engage said notched edge of the plate and retain said arm in a predeterminate position.

4. in automobile signalling device, comprising, in combii'iation an upright bar adjustably secured to the windshield rail of the automobile by means of a pair of clamps,- 41 bracketmountedupon said upright bar be tween said clamps and' supported thereby, 1311155 upon said clamps to hold said bracket in rigid position, arm pivotally connected to said bracket adapted to hang downward against the face of the bracket and swing upward and outward therefrom, mechanism tor operating said arm, consisting of a pin to projecting backward from said bracket can] in testimony that I claim the foregoing i have hereto set my hand in the presence-of two Witnesses, this 18th day'of February 1990;
